Ich on my Angelfish?

[bblacrosse]

Couple days ago my I discovered that my angelfish, Moo, had a big white spot on his left fin. Is it ich? I have some pics. What should I do about it?
Sorry the pics are all the same

Yep looks like he's damaged it. Anybody nipping him? My angelfish has just gone through being nipped, torn fins etc plenty off extra water I did mine every second day & she's as good as new

But he's the big fish in the tank, and none of the other fish nip him, so I don't know what's happening

Has he maybe caught himself on something? Keep an eye on him,plenty off clean water helps & if it gets worse get back to use
